Design and implementation of an ultrasonic sensor for the educational platform
Slabý, Vojtěch ; Bastl, Michal (referee) ; Spáčil, Tomáš (advisor)
Bachelor’s thesis is focused on a design, fabrication and implementation of an ultrasonic sensor module, which will serve for a distance measurement for an education developer shield based. This sensor should be used as an original module which fits in a requested size format. Now is used a sensor HC-SR04 which exceeds size and voltage needed for a module and uses an adapter, which is not rigid. Bachelor’s thesis is focused on a topic of a existing ultrasound principles and its function for ultrasound distance measurement and calculating necessary values. Thesis includes a list of existing solution for designing a monostatic or a bistatic transdcuers sensors. Our module is compared to those solutions and there is also an overview on a two most used methods for a circuit design which controls a transducer. You can find a designed circuits for creating a prototype PCBs, which heart is a microcontroler PIC16F1769. Programming is handled by a PicKit 3, MPLab X IDE in „C“ language. Communication with a Jobst shield is handled by SPI. Result of this thesis is a design, fabrication and use of two prototype PCBs. First PCB is not tied by a size request and serves for a basic circuit testing and basic distance measurement and the second PCB is in a desired size and serves for distance measurement testing and communication via SPI. These prototypes were fabricated and tested in a way to fulfill set task goals.
